Clinical information about Diabetes Type 1:

Type 1 Diabetes is a lifelong chronic medical problem characterized by the pancreas producing little to no insulin. This is a life-threatening problem because insulin is an essential hormone. It is what regulates glucose in our blood, and it helps our bodies use glucose for energy.

Type 1 Diabetes is characterized by the immune system destroying insulin-producing cells in the pancreas. This can lead to an overabundance of glucose in the body (hyperglycemia). If there’s too much glucose in the body, the person is at risk of complications like stroke, heart disease, kidney damage, nerve damage, retinopathy, and even death.

Those with this type of Diabetes must take insulin externally via insulin shots or pumps for the rest of their lives.

Commonly asked questions

Even with current research, the exact causes haven’t been confirmed, but findings suggest genetics have something to do with it. Those who have had relatives who’ve had Type 1 Diabetes have a higher chance of possibly getting it than those who don’t come from a line of Type 1 Diabetics.

Since it’s not known what exactly causes it to develop, there are no ways of preventing it.

If by normal, you mean being able to work, do the things they love doing, and do other activities, then yes, they can live “normal” lives. They just need to properly manage their insulin levels by regularly taking insulin shots or pumps, monitoring their blood levels consistently, and making lifestyle adjustments (e.g., dietary adjustments, regular exercise, stopping smoking, avoiding or lessening alcohol consumption).
